What these figures can't tell you
An MOT is a safety and emissions test. These figures show how often the model fails that test. They say nothing about engines, gearboxes or electronics that break between tests, and how a car has been looked after matters more than its badge. The car you are looking at has its own MOT record, and that is the one to read.
Ask before you travel
- “How much tread is left on each tyre, and how old are they?”
- “Do all the lights work, including the number plate lights and brake lights?”
- “Is there any corrosion underneath or around the sills and arches?”
- “When were the brake pads and discs last changed?”
